摘　　要：基于投影矩阵算法和最小熵概念,本文提出了处理含部份未知成份体系的定性定量分析新方法。将此法应用于金属离子及多环芳烃混合物体系测定,获得了满意的结果。A new chemometrics algorithm of spectral multivariate analysis has been developed for systems containing unknown interfering components. The algorithm is based on matrix projection procedure and minimum entropy concept. No reference spectra of possible interferences from the library is required. Good results with visible absorption spectra of metal-ion mixtures and fluorescence spectra of mixtures of polycyclic aromatic compounds demonstrate the effectiveness of the method.
